Bosch Claims New Diesel Technology Cuts NOx Emissions

It says that in RDE (real driving emissions) testing, emissions from vehicles equipped with its new diesel technology are not only significantly below current limits, but also those scheduled to come into force from 2020.

Since 2017, European legislation has required that new passenger car models tested, according to an RDE-compliant mix of urban, extra-urban, and motorway cycles, emit no more than 168 milligrams of NOx per kilometre. As of 2020, this limit will be cut to 120mg.

Bosch claims that, in tests, vehicles equipped with its diesel technology achieved as little as 13mg of NOx in standard legally-compliant RDE cycles. That is approximately one-tenth of the EU limit that will apply after 2020. And even when driving in particularly challenging urban conditions, where test parameters are well in excess of legal requirements, the average emissions of the Bosch test vehicles, it says, are as low as 40mg/km.
